61: The options are as follows:
1.13 aaron 62: .Bl -tag -width Ds
1.21 ! jmc 63: .It Fl a
! 64: Display all of the manual pages for a specified
! 65: .Ar section

! 68: combination.
! 69: (Normally, only the first manual page found is displayed.)
! 70: .It Fl C Ar file
! 71: Use the specified
! 72: .Ar file
! 73: instead of the default configuration file.
! 74: This permits users to configure their own manual environment.
! 75: See
! 76: .Xr man.conf 5
! 77: for a description of the contents of this file.
! 78: .It Fl c
! 79: Copy the manual page to the standard output instead of using
! 80: .Xr more 1
! 81: to paginate it.
! 82: This is done by default if the standard output is not a terminal device.
! 83: .It Fl f Ar command
! 84: Locate man pages matching the
! 85: .Ar command
! 86: in much the same way
! 87: .Xr whatis 1

1.8 aaron 94: Locate man pages matching
1.7 deraadt 95: .Ar keyword
96: in much the same way as
97: .Xr apropos 1
98: works (in fact, it runs
1.21 ! jmc 99: .Xr apropos 1 ) .
1.7 deraadt 100: This can be used to find which man page applies to a particular subsystem
1.21 ! jmc 101: you are interested in.
! 102: For instance:
1.7 deraadt 103: .Pp
1.21 ! jmc 104: .Dl $ man -k mount
1.7 deraadt 105: .Pp
1.21 ! jmc 106: will list all man pages which contain
1.7 deraadt 107: .Ar keyword
108: in the
1.21 ! jmc 109: .Dq NAME
1.11 deraadt 110: line of the man page;
111: in this case a list much like this:
